EDWARD G. BUDD, OF PHILADELPHIA, PENNSYLVANIA. ASSIGNOR 'IO'HALE-KILBURNMETAL COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN-SYLVANIA'.

To all whom it may concern:

Be it known that I, EDWARD Gr. Bonn, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMetallic Sheathing, of which the following is a specification.

This invention relates to metallic sheathling of the type disclosed inan application.

for Letters Patent filed by me August 20th, 1907 and serially numbered389,325.

Myimproved sheathing is of particular utility as a lining for theinterior and exterior of railway cars, although it is, of course,susceptible of use in other relations as well.

The invention is directed to the provision of an improved sheathingconsisting of a multiplicity of metallic sections adapted to beassembled edge to edge and provided with interlocking parts whichposition the sections relatively, these sections being individuallyremovable so that in case of local damage such sections as may benecessary may be withdrawn and new ones substituted in their places.These sections of the sheathing are made of sheet-metal pressed to thedesired form so that they may be manufactured at very low cost, andbecause of the fact that the sections are quite narrow, although metalof light weight is employed, the completed structure will possess amplestiffness and rigidity. The several sections of the sheathing are eachprovided with a body portion and edge portions at the lateral edgesthereof so constructed as to provide for the interlocking of the severalsections with each other or with the supporting structure, theseinterlocking parts being arranged to hold the sections in position withthe body portions thereof forming a substantially unbroken wall. Thespaces behind this wall and between the edge portions of the sectionsmay form dead air cells which prevent radiation of heat to a very largeextent, or if desired, these spaces may be filled with a heat insulatingmaterial as cork or asbestos. Such a sheathing is of great utility as alining for the exterior of a railwaycar as a substitute for the largesheet-metal plates now employed for this purpose, particularly as incase of damage only such sections of the sheathing as may have beendamaged need be withdrawn and replaced by new Specification of LettersPatent.

ones, whereas, when the large sheet-metal plates are employed acomparatively small injury to the car necessitates the removal of atleast one such large sheet, if not the covering for the entire side ofthe car.

Furthermore, with the sectional sheathing as herein disclosed, a moreattractive appearance is presented since no rivets show upon theexterior of the car, radiation of heat is reduced to a large extent,rattling and reverberation of sound are minimized and a considerablereduction in the cost of construction is 'efl'ected.

I have illustratedembodiments of my invention by which these objects areattained in the accompanying drawings in which Figure 1 is a verticalsection through the side of a car, Fig. 2 is an elevation of a portionof the side of a car, Fig. 3 is a section through the sheathing, Fig. 4:is a view similar to Fig. 3 illustrating a modified form of sheathing,Fig. 5-is a perspective view illustrating a form of sheathing closelysimilar to that illustrated in Fig. 4. and Fig. 6 is a view similar toFig. 5 illustrating a further modification of the invention.

Referring to these drawings, 1, 2, 3 and 4 indicate sections of thesheathing, each formed of a strip of sheet-metal, preferably steel,pressed to provide a body. portion 5 and edge portionsfi and 7 at thelateral edges of and integral with the body portion 5, these edgeportions being turned at an "angle of ninety degrees to the bodyportion.

At the extreme edges of the strips for the sections, flanges Smay beprovided turned toward each other, as shown, and disposed parallel tothe body portion 5. In pressing the sections into form a rounded groove9 is formed in the edge portion 6 preferably at about the center thereofand in the edge portion 7 a corresponding bead 10 is formed, thesegrooves and beads extending throughout the length of the sections. Thesections thus constructed are assembled edge to edge as shown with thebead of each section entering the groove in the adjacent section'andwhen thus positioned the body portions 5 of the several sections lie inthe same plane so as to form a wall which is unbroken except for theslight depressions at the joints between the sections which extendacross the sheathing in parallel lines as shown in Fig. 2.

- -Figs.- 1 and 2 show the sheathing as applied to the exterior or toboth the exterior and interior of the side wall of a car. The car itselfmay be of the usual or any suitable construction, it being here shown asprovided with an underframe 11 supporting the floor 12, a roof 13 andsupports 14, as a suitable metallic truss-work, for supporting the roof13 upon the under-frame 11. The sheathing is applied to the outer sideof the car to cover this truss-work as at 15, and if desired, a similarsheathing 16 may be applied over the inner side of the truss-work.

Any suitable means may be employed for holding the sheathing inposition. In Figs. 1 and 2 I have shown metallic pieces 17 and 18 ofchannel section extending along the bottom and top edges of the side ofthe car, these being adapted to receive the ends of the sections of thesheathing so as to retain them in position. When the sections are inposition the body portions 5 thereof form an unbroken wall and movementof any section relatively to the sections adjacent thereto such as wouldcarry the body portion 5 thereof out of the plane of this wall isprecluded by the coact-ion of the beads 10 and grooves 9 of adjacentsections.

In Fig. 3 I have shown the sectional sheathing applied over the surfaceof a piece of sheet-metal 17 though it will be seen that the provisionof such a sheet is by no means essential in this form of sheathing.WVhen such a sheet is provided the flanges 8 on the sections of thesheathing, lie against the sheet 17 to assist in properly positloningthe sections relatively.

In Figs. 4 and 5 I have shown a sheath ing of a slightly modifiedconstruction the difference being that edge portions of the sections ofthese sheathings are shaped to coact, not with each other, but withparts mounted on the supporting structure. Referring to Fig. 1 it willbe seen that a sheet 17 is provided as before and to this are secured aplurality of strips 18 of metal, fiber or any other suitable material,the sides of which diverge as shown. Each section of the sheathing isprovided with body and edge portions and these edge portions are formedto coact with the strips 18. Thus it will be seen that the edge portions19 of adj acent sections lie side by side and that beyond these portionsthe metal of the sections is bent to conform to the shape of the strips18. The sheet 17 with the strips 18 attached thereto may be supplied insizes as desired and in assembling the structure the sections of thesheathing are cut to the desired length and are forced lengthwise intoposition with the edge portions thereof coacting with the strips 18. Itwill be seen that because of the inclination of the sides of the strips18 and the corresponding configuration of the edge portions of thesections of the sheathing, the latter will be held in position with thebody portions 20 thereof forming a substantially unbroken wall; alsoshould any one or more of the sections become damaged it can bewithdrawn lengthwise and a new one inserted in its place. Instead ofemploying solid strips 18 the same purposes may be served by theprovision of strips formed of sheet-metal by bending the lateral edgesof a sheet-metal strip upwardly from the portion lying between them soas to provide divergil'ig flanges at the sides of the strip. Such aconstruction is shown in Fig. 5 in which the sheet 17 is shown as havinga plurality of sheet-metal strips 21 secured thereto parallel to eachother, each of these strips being provided with integral divergingflanges 22. In other respects the construction here illustrated is likethat shown in Fig. 4:, the change merely effecting a reduction in thecost of construction.

Referring to Fig. 6 a further modification of the construction of thesectional sheathing is illustrated. Each of the sections of thissheathing is provided with a body portion 23 and integral edge portions24 and 25, and these edge portions are constructed to provide thedesired interlock of adjacent sections. On each edge portion 21 are aplurality of extensions or tongues 26 disclosed in a plane parallel tothe plane of the body portion 23. Between these extensions the metal ofthe edge portion 24L is cut away slightly as shown at the right of Fig.6. On each of the edge portions 25 are a plurality of similar extensions27, each of these extensions being located opposite the space betweenadjacent extensions 26 on the edge portion 24 and the edge portion 25being similarly cut away between the extensions 27. In assembling thissheathing, one section is mounted in position and then the tongues 27 onanother section are inserted in the spaces formed by cutting away themetal of the edge portion 24 of the section first positioned between theextensions 26 of that section and the section is then moved sidewisebodily until the edge portion 25 thereof abuts against and lies parallelto the edge portion 24 of the section first positioned. Other sectionsare then assembled in the same manner.

Vith the construction herein disclosed numerous and important advantagesare secured. A sheathing is provided which consists of a multiplicity ofcomparatively narrow sections so that in case of local damage any one ormore sections, as may be necessary, can be withdrawn and perfect onessubstituted in place thereof; the securing means for holding thesections in position is concealed so that a more attractive appearanceis presented particularly as the employment of rivets which would showon the exterior of the sheathing, is avoided; as the sections of thesheathing are quite narrow and as the body portions thereof are bracedby the edge portions which are disposed at an angle thereto, thin, lightmetal may be employed in the manufacture of the sheathing without asacrifice in the stiffness of the completed structure; the spaces withinthe sections aid materially in precluding the radiation of heat, thesespaces merely forming dead air cells or being filled with powdered cork,asbestos or like heat insulating material.

For securing the sheathing in position, the channel bars 17, 18 may berelied on to hold the ends of the sections and if desired the sectionsmay be bowed somewhat to place them under tension as disclosed in myapplication above referred to. Instead of or in addition to the channelbars, the sheet 17 may be employed to which the sections of thesheathing are afiixed; these sheets 17 may be supplied in such sizes asmay be required by the use to which the sheathing is to be put. Withsheathing of the forms shown in Figs. 3 and 6, the flanges 8 may beafiixed to the sheet 17 in any suitable manner, though with thissheathing I find it preferable to rely on the channel bars for holdingthe sections in place. WVith sheathing of the forms shown in Figs. 4:and 5, the large sheets 17 are provided with the strips 18 or 21attached thereto so that when secured in position, the sections of thesheathing can be readily mounted thereon.

Having described my invention what I claim as new therein and desire tosecure by Letters Patent of the United States is:

l. The combination of a support, a plurality of strips having divergingside walls secured thereto, a sheathing consisting of a plurality ofsheet-metal sheathing sections each having a body portion and edgeportions turned at an angle to the body portion, said edge portionscoacting with the side walls of said strips to hold the sections inposition with said body portions forming a substantially unbroken wall,and end strips of angular cross-section extending transversely to saidsections and receiving the ends thereof, substantially as set forth.

2. The combination of a support, a plurality of sheet-metal stripssecured thereto having the lateral ed 'e portions thereof bent to formdiverging si e walls, and a sheathing consisting of a plurality ofsheet-metal sections coacting at their lateral edges with the side wallsof said strips to hold the sections in position, substantially as setforth.

ing consisting of a plurality of sheet-metal sheathing sections eachhaving a body portion and edge portions lying at an angle to the bodyportion, said edge portions coacting with the side walls of said stripsto hold the sections in position with said body portions forming asubstantially unbroken wall, substantially as set forth.

4. The combination of a support, a plurality of stri s secured thereto,a sheathing consisting of a plurality of sheet-metal sheathing sectionseach having a body portion and edge portions lying at an angle to thebody portion, said edge portions coacting with said strips to hold thesections in position with said body portions forming a substantiallyunbroken wall, said sections being individually removable in thedirection of their length and formed to provide spaces between them andsaid support, and end strips of angular cross-section extendingtransversely to said sections and receiving the ends thereof,substantially as set forth.
